Why quarter of the window go dark
The inspector and other windows always turned into that look I submit below, up right quarter goes dark. I switch the unity version many times, but it is still there. 
I'm using GTX1070, the other working is good, game playing is good, just Unity has this problem. I‘m using free licence, and there is no function problem, just the quarter twinkling between normal and dark gray. I used a lot of version of unity from 5.x to 2018.x, it never changed, so I thought it might be some setting problem or graphic card problem. Will someone help me ? It might be unusual and insignificance, but really annoying.
